ABSTRACT:
A glass material for a substrate, or a glass substrate, consists essentially of the following glass ingredients: from 45 to 70 wt % of SiO2, from 1 to 10 wt % of Al2O3, from 0.5 to 8 wt % of B2O3, from 7 to 20 wt % of Li2O+Na2O+K2O, from 0.1 to 10 wt % of MgO, from 0.1 to 10 wt % of CaO, from 1 to 15 wt % of MgO+CaO, from 0.5 to 10 wt % of TiO2, from 0.5 to 10 wt % of ZrO2, from 0 to 5 wt % of ZnO, and from 0 to 8 wt % of La2O3. The glass material, or the glass substrate, has uniform composition between at the surface and in the interior and has an amorphous structure. With this design, it is possible to obtain high mechanical strength without strengthening treatment, a linear thermal expansion coefficient close to motor components, and excellent chemical durability.
